| 摘 要： | 以2年生接骨木无性系硬枝为试验材料，对其扦插最适生根剂种类及浓度进行探讨。结果表明：生根剂ABT1、NAA、IBA对接骨木硬枝扦插生根率平均值分别为62.5%、71.6%、73.4%，其中200 μg/mL的NAA处理2 h，平均扦插生根率达80.6%；枝条下部(80.5%)、中部(78.3%)的插穗生根效果明显优于上部(51.4%)；不论哪种生根剂，上部插穗的平均根长及根数均小于中部和下部；不同部位插穗平均叶片数变化不大，而抽枝长度变化较大，其中下部插穗在200 μg/mL的NAA处理2 h，平均抽枝长度达15.75 cm。接骨木硬枝扦插以愈伤组织生根为主，属于愈伤组织生根类型。结合生根率及各生长性状综合评价接骨木硬枝扦插繁殖效率，最适生根剂种类及浓度为100 μg/mL的NAA处理1 h。研究结论对提高接骨木硬枝扦插繁殖系数具有重要意义。

Sambucus williamsii Hance.: Cutting Propagation Technology of Hard Branch |
| |
| Abstract: | With 2-year-old clones hardwood of Sambucus williamsii Hance as test materials, the optimal rooting agent and concentrations are discussed about hard branch cuttings in Sambucus williamsii Hance.Test results show that:The average rooting rates of Sambucus williamsii hardwood cuttings was 62.5%, 71.6% and 73.4%, respectively,under the treatment of rooting agents ABT1, NAA, IBA, among them,?200μg/mL of NAA was treated for 2h, and the average cutting rooting rate was 80.6%; ?The rooting effect of the lower part of the branch (80.5%) and the middle part (78.3%) was significantly better than that of the upper part (51.4%);no matter what kind of rooting agent,the average root length and number of roots of the upper cuttings were smaller than the middle and lower parts;?The average number of leaves in different parts of the cuttings did not change much,while a larger change in length of the branch?, the lower cuttings were treated with 200μg/mL NAA for 2h, and the average length was 15.75 cm.?Hardwood cutting of Sambucus williamsii Hance dominated by callus rooting, callus rooting type belongs to.?Based on the combination of rooting rate and growth character, the efficiency of hardwood cutting propagation was evaluated comprehensively in Sambucus williamsii Hance，?The optimum rooting agent type and concentration was 100μg/mL for NAA treatment for 1h.The conclusion of the study is of great significance to improve the propagation coefficient of hardwood cuttings of Sambucus williamsii Hance. |
